The Core
The core consists of two parts: the inner core and outer core. The outer core begins about 2,900 kilometers below the earth's surface. Scientists believe that the outer core is about 2,250 kilometers thick and is made o..

Construction
It consists of a soft iron core made of laminated sheets well insulated from each other. The coils P 1 P 2 and S 1 S 2 are wounded on the same core. The coil P 1 P 2 is a primary coil connected to AC source and S 1 S 2 is a se..

The outermost shell of an atom is known as the valence shell. The electrons present in the valence shell are called valence electrons. K L M Na - 11 - 2 8 1 Valence shell - M Valence electrons - 1 Core electrons - 2 + 8 = ..
The Universe Summary
>The earth consists of three major layers, which are the crust, mantle and core. The outermost layer of earth is called crust. The central region between the crust and core of the earth is called mantle. The innermost part of earth is called its core. A star is made up mainly of..
The Life of a Star
This energy further increases the temperature and pressure inside the star. A star has a core and an outer shell. The internal pressure created due to the energy released during fusion stops the core from collapsing. The star is in a delicate equilibrium under two opp..

Tutor Vista teachers were knowledgeable and good in explaining to kids with 100% correct answers.... Landon
It is a really good tutoring. The tutors are thoughtful, helpful, active to help students. A lot of ideas they have. Encouraging students too. -Riley
I uploaded a worksheet and I wanted to follow it with the tutor so I could learn the technical parts. It took just a few minutes to get the understanding of what I needed with the tutor. I even get through all the examples on the sheet in 25 minutes that we were focused on it.
I have experienced very innovative way of learning, I joined online tutoring at Tutorvista few months back when I was in grade 10, I scored really well in grade 10 and ny parents were really happy.
